Explanation / Answer

Given Data

charges q 1 = 1.17 C

              q2 = 6.94 C

             q 3 = - 4.75 C

             q 4 = - 9.46 C

if they are in contact with each other then net charge on fourmetallic

objects = q 1+ q 2+ q 3 + q 4

            = 1.17 C + 6.94 C - 4.75 C - 9.46 C

            = - 6.1 C

( a ) . final charge on each object = ( - 6.1 C ) /4

                                                 = - 1.525 C

                                                 = - 1.525 * 10 -6 C

( b ) . charge is - ve .So ,it contain electrons

         charge on the electron q = 1.6 * 10 -19 C

          No . of electron each object = ( 1.525 * 10 -6 C ) /(  1.6 * 10 -19 C )

                                                 = 9.53*10 12

         i.e., each object have 9.53*10 12 electrons
